Ingabe i-Cold Saw iyindlela enhle yokukhetha isicelo sakho se-Metal Cutoff?

Ngaphambi kokuthi ukhethe ukusaha okubandayo kwengxenye yakho yensimbi engu-2-eksisi, kubalulekile ukuqonda izinzuzo kanye nobubi benqubo. Ngaleyo ndlela, ungahlola futhi unqume ukuthi - noma iyiphi enye indlela yokusika insimbi enembayo ongase uyicabangele - izohlangabezana nezidingo zakho nezinto eziza kuqala.

Ama-Hard Blades Wokusika Ngokushesha

I-cold sawing isebenzisa i-blade eyindilinga ukuze isuse izinto ngenkathi idlulisela ukushisa okukhiqizwa kuma-chips adalwe yi-saw blade. Isaha elibandayo lisebenzisa insimbi eqinile enesivinini esikhulu (HSS) noma i-tungsten carbide-tipped (TCT) blade ejika ngama-RPM aphansi.

Ngokuphambene negama, ama-HSS blades awavamile ukusetshenziswa ngesivinini esiphezulu kakhulu. Esikhundleni salokho, isici sabo esiyinhloko siwubulukhuni, okubenza bakwazi ukumelana nokushisa nokugqoka. Ama-TCT blades abiza kakhulu kodwa futhi aqinile ngokwedlulele futhi ayakwazi ukusebenza emazingeni okushisa aphakeme ngisho nangaphezulu kune-HSS. Lokhu kuvumela amasaha e-TCT ukuthi asebenze ngamanani ashesha kakhulu kunama-HSS blades, kunciphisa kakhulu isikhathi sokusika.

Ukusika ngokushesha ngaphandle kokukhiqiza ukushisa nokungqubuzana okukhulu, izindwani zomshini wokusaha ezibandayo zimelana nokugqoka ngaphambi kwesikhathi okungase kuthinte isiphetho sezingxenye ezisikiwe. Ngaphezu kwalokho, zombili izinhlobo zama-blades zingalola kabusha futhi zingasetshenziswa izikhathi eziningi ngaphambi kokuba zilahlwe. Le mpilo ende yensingo isiza ukwenza ukusaha okubandayo kube indlela engabizi kakhulu yokusika ngesivinini esikhulu kanye nokuqedwa kwekhwalithi ephezulu.

Cold Sawing Izinzuzo

Amasaha abandayo angasetshenziselwa ukusika izimo eziningi ezihlukene, okuhlanganisa izinduku, amashubhu, kanye nama-extrusions. Amasaha abandayo ayindilinga azenzakalelayo, avalelwe asebenza kahle ekugijimeni kokukhiqiza namaphrojekthi aphindaphindayo lapho ukubekezelelana nokuqeda kubalulekile. Le mishini inikezela ngesivinini se-blade esiguquguqukayo kanye namazinga okuphakelayo alungisekayo okukhiqiza ngesivinini esikhulu kanye nokusikeka okungenama-burr, okunembile.

Ngensingo enhle, ebukhali, isaha elibandayo eliyindilinga elisheshayo linezinzuzo zokucishe likhiphe ama-burrs futhi lingakhiqizi izinhlansi, ukushintsha umbala noma uthuli. Ngakho-ke, indlela ngokuvamile iletha isiphetho sekhwalithi ephezulu enemiphetho yeqiniso.

Inqubo yokusaha ebandayo iyakwazi ukuphumela phezulu ezinsimbi ezinkulu nezisindayo - ezimeni ezithile, iqine njengo ±0.005” (0.127 mm) ukubekezelela. Amasaha abandayo angasetshenziselwa ukusika kokubili izinsimbi ezisansimbi nezingezona ayoni, kanye nokusikeka okuqondile nokunama-engeli. Isibonelo, amamaki avamile ensimbi abolekisa ekusaweni okubandayo, futhi anganqanyulwa ngokushesha ngaphandle kokukhiqiza ukushisa nokungqubuzana okuningi.

Ezinye I-Downsides Ukuze Amasaha Abandayo

Nokho, ukusaha okubandayo akulungile ngobude obungaphansi kuka-0.125” (3.175 mm). Ukwengeza, le ndlela ingakwazi ukukhiqiza ama-burrs anzima. Ngokukhethekile, inkinga lapho unama-OD angaphansi kuka-0.125” (3.175 mm) kanye nakomazisi abancane kakhulu, lapho ishubhu lalizovalwa khona i-burr ekhiqizwa isaha elibandayo.

Okunye okungekuhle kumasaha abandayo ukuthi ukuqina kwenza amasaha abe brittle futhi akwazi ukwethuka. Noma yiliphi inani lokudlidliza - isibonelo, kusukela ekubambeni okunganele kwengxenye noma izinga lokuphakela elingalungile - lingalimaza kalula amazinyo asaha. Ngaphezu kwalokho, amasaha abandayo ngokuvamile abangela ukulahlekelwa okukhulu kwe-kerf, okuhumushela ekukhiqizeni okulahlekile kanye nezindleko eziphezulu.

Nakuba i-sawing ebandayo ingasetshenziselwa ukusika ama-alloys amaningi ane-ferrous ne-non-ferrous, akunconywa ngezinsimbi eziqinile kakhulu - ikakhulukazi, lezo eziqinile kunesaha ngokwalo. Futhi ngenkathi amasaha abandayo ekwazi ukusika inqwaba, angakwenza kuphela ngezingxenye ezincane zobubanzi futhi kudingeka ukulungiswa okukhethekile.

Ukukala Izinketho

Ukunquma ukuthi usebenzise i-sawing ebandayo kudinga ukuqonda okujulile kohlelo lwakho lokusebenza oluhlukile kanye nemingcele yalo ethile. Ukwenza ukukhetha okungcono kakhulu kudinga nokuqonda izindlela ezahlukene ezisetshenziselwa ukusika insimbi.
